ROTARY GAN-TIPPING MACE-ENE.

Patented Oct. 12, 1915 Application filed January 7, 1915. Serial No. 964.

To all who-m it may concern:

Be it known that I, HAROLD E. SHAw, a citizen of the United States, residing at lvlaywood, in the county of Cook and State of Illinois, have invented certain new and cient and rapid, thus insuring a great saving of time and expense and the highest degree of efiiciency. 7

Another object of my invention is the provision of a machine of the character and for the purpose stated, which will insure the melting and application of the solder in a smooth and even manner and which will be capable of adjustment to guide and accommodate cans of varying sizes.

Another object of my invention is the provision of a machine which will insure a saving of time and a high degree of efliciency and which will be small and compact in size, simple, strong and durable in construction and inexpensive; to possess the requisites, to insure a thoroughly reliable and practical improvement.

With these objects in View my invention consists of a machine for sealing center vents in cans, embodying novel featuresof construction and combination of parts for service, substantially as disclosed herein.

In order that the detailed construction and operation ofmy machine may be fully understood and its many advantages and features of merit be appreciated, I have shown in the accompanying drawings a ma chine constructed in accordance with my invention. I V.

Figure 1 represents a top plan view of the complete machine. Fig. 2 represents a side elevation thereof. Fig. 3 represents one of the plates which are secured to the rotary carrier or star wheel for varying the adjust ment of said wheel to suit the can, and Fig. 4; represents a detail view of an adjustable means to be applied to the track at the exit of the can. a

Referring by numeralsto the drawings in which similar numerals denote like parts in the four views, the numeral'l designates the bed or base, from which depend the pair of lugs 2, for securing the base to a suitable support, the standards being connected by the top bar or plate 3, and at onev side of the bed travels the endless belt'or apron 4. The said belt is of any desired construction and is suitably driven and in proper relation thereto, and to the machine is .mounted supports '5, to which are secured curved'guides 6, and in parallel relation to sald pair of guides 6 are supported by posts 7 and threaded rods 8, the guides 9. This construction provides with reference or relation to the belt an entrance guide and an exit or discharge guide for the cans '10, whose central vent'opening 11,.is to be supplied with the desired amount of solder, thesaid guides being thus disposed in proper position to the can. guiding rail '12, retained by the series of adjustable rods 13, and

posts 14,- in which said rods 13, are mounted.

It will thus be seen that the guiding rail 12 and the entrance and eXit guides 6 and 9, are arranged in suchmanner with reference to the endless belt, that the can is carried by said belt and received andconducted by the entrance guide'u pon the bed and is delivered or discharged upon said belt by the exit guides after being operated upon by mechanismlwhich'l will now'describe.

In the bed of themachine is an opening- 15, forming the bearing for the vertical shaft 16, mounted for rotation upon thethreaded spindle 17, and driven by suitable power, and-upon the shaft 16, is secured by ,means of the sleeve 18, the rotary carrier or contact with the rail 12, and Whensoldered discharge the can at the exit 22, as indicated by the arrows. To ad ust the pockets according to the size of the cans the strips 23 are provided, which are secured to the wheel by fastenings as. From this construction it will be'seenv that the cans are fed from the belt to the bed of the machine and are guided by the rail and guides, and carried continuously from their entrance to exit by the rotary wheel, and that the cans are revolved by contact with the pockets of the wheel and guide rail, and upon the shaft 16, at its up per end, is secured the gas chamber 25, hav ing the feed pipe 26, rotatably mounted by means of the cap 27 in the cross-bar or plate 3.

The gas chamber is in communication with the upply, and has mounted therein the series of branch pipes 28, having regulating cocks 29, the branch pipes communicating by means of the pivoted nipples 30, with the steel or implement feeding pipes 31, from which depend the solderin steels It will thus be seen that the gas chamber with the series of connections revolve and that the said connections permit a raising and lowering of the steels and that the steels are disposed over the closure of the pockets to bring them directly above the center vent opening of the cans.

To the steels are secured the studs 33, upon which are mounted the rollers 34:, which travel upon the track. 35, supported by the pair of yokes 36, and the portion '38 of the track is in a higher plane than the portion 37, the purpose of which is to hold the steels in elevated position. while on the raised portion 38, thus providing the cans free entrance to, and exit from the machine and at the same time allowing the steels to fall when entering the depressed portion 37 and this permits the steels to contact with the solder thereon and effect the sealing of the vent opening while the steel is traveling in lowered position upon the depressed portion of the track. I

It will be seen that the can is directed by the guides into one of the pockets of the wheel and revolved with the steel in elevated position above the center opening of the can and in this position as soon as the roll enters upon the depressed portion of the track, the steel upon which it ismounted drops upon the opening ofthe can, and the vent opening is sealed by the solder.

The device shown in Fig. 4-, is attached to the track at the end of depressed portion 3'7 and consists of a plate 39, having slotted ends 40, adjustable on pins ll, to regulate the time the steel shall travel on the track in finishing the soldering.

From the foregoing description taken in connection with the drawings the operation and advantages of my machine will be readily understood and it will be observed that the cans are fed from the belt to the bed, and are received and carried by the wheel,

, and that the steels melt the solder while the cans revolved, and that when the sealing is completed the cans are directed to the belt and carried away in finished condition, thus saving a great amount of time and eX pense, and performing the service in a thoroughly eiiicient manner.

it will be noted that the cans are operated upon successively and automatically; that each can receives the same treatment; that the machine is small and compact in size, while of large handling capacity; is easy to control and inexpensive to maintain; and that generally speaking is thoroughly eflicient and practical.
